Visible-Light-Promoted Unsymmetrical Phosphine Synthesis from Benzylamines

Herein, by applying visible-light photoredox catalysis, we have achieved the catalytic deaminative alkylation of diphenylphosphine and phenyl phosphine with benzylamine-derived Katritzky salts at room temperature. The use of Eosin Y as photoredox catalyst and visible light can largely promote the reaction. A series of unsymmetrical tertiary phosphines were successfully synthesized, including phosphines with three different substituents that are otherwise difficult to obtain.

Ni-Catalyzed Asymmetric Hydrophosphination of Unactivated Alkynes

The practical synthesis of P-stereogenic tertiary phosphines, which have wide applications in asymmetric catalysis, materials, and pharmaceutical chemistry, represents a significant challenge. A regio- and enantioselective hydrophosphination using cheap a

Bis(alkyl) scandium and yttrium complexes coordinated by an amidopyridinate ligand: Synthesis, characterization and catalytic performance in isoprene polymerization, hydroelementation and carbon dioxide hydrosilylation

New neutral bis(alkyl) Sc and Y complexes [N,Npy,N-]Ln(CH2SiMe3)2(THF)n [n = 0, Ln = Sc (1Sc), Y (1Y); n = 1, Ln = Y (1YTHF)] stabilized by a tridentate monoanionic amidopyridinate ligand were straightforwardly prepared by alkane elimination, upon mixing ligand [N,Npy,N-]H and metal precursor Ln(CH2SiMe3)3(THF)2 in toluene at 0 °C. Depending on the work-up conditions, yttrium bis(alkyl)s were isolated as either a pentacoordinate Lewis base free complex [N,Npy,N-]Y(CH2SiMe3)2 (1Y) or as a hexacoordinate THF adduct [N,Npy,N-]Y(CH2SiMe3)2THF (1YTHF). For the smaller Sc ion the only solvent-free complex [N,Npy,N-]Y(CH2SiMe3)2 (1Sc) was isolated as a pentacoordinate species irrespective of the reaction/work-up/crystallization conditions applied. Complexes 1Ln (Ln = Y, Sc) and 1YTHF were scrutinized as pre-catalysts in ternary catalytic systems Ln/borate/AliBu3 (borate = [HNMe2Ph][B(C6F5)4] or [Ph3C][B(C6F5)4]), applied to isoprene (IP) polymerization, providing moderate activity albeit high selectivity with predominant formation of 1,4-cis polyisoprene (up to 99%). The same complexes proved to be effcient catalysts also for the intermolecular hydrolelementation of styrene with various EH sustrates (pyrrolidine, morpholine, Ph2PH, PhPH2, PhSH) affording linear anti-Markovnikov addition products exclusively. After a preliminary activation by B(C6F5)3, selected bis(alkyl) complexes from this series have been finally used as valuable pre-catalysts for the CO2 hydrosylilation to CH4 in the presence of organosilanes as reducing agents (PhMe2SiH, PhSiH3, Et2MeSiH).

Resolution of secondary phosphanes chiral at phosphorus by means of palladium metallacycles

The synthesis of new epimeric compounds [PdCl(C-N){(±)-PHPhR}] (C-N = (R)-C10H6CHMeNH2 and (R)-C6H4CHMeNH2, R = Me and PhCH2) containing chiral secondary phosphanes is reported. Some of these diastereomers can be separated by column chromatography; subsequent re- action of these complexes with 1,2-bis(diphenyiphosphanyl)-ethane (dppe) affords the free phosphanes PHBzPh and PHMePh. The configurational stability of the secondary phosphanes resolved has also been studied.

Synthesis and resolution of a new P-chiral hydroxy phosphine

The synthesis of the functionalized P-chiral phosphine BzPhP{CH(OH)Ph}and its resolution by palladium metallacycles is reported. The cyclopalladated compound containing the primary amine 1-(1-naphthyl)ethylamine has been shown to be a better resolving agent for this phosphine than the corresponding metallacycle containing the tertiary amine N,N-dimethyl-1-(1-naphthyl)ethylamine

Secondary and tertiary phosphines (RR'PH; R2R'P) may be synthesized by alkylation of primary or secondary phosphines with organo halides (R' = Et, n-C7H15, Bz, Me3Si; X = Cl, Br) in the presence of Schwesinger bases as auxillary bases in high yields.Alkylation of diphenylphosphine with alkylene dihalides and Schwesinger bases affords alkylendiphosphines.
